Very nice to see more tuned F10 M5's hitting the streets and this vehicle in particular features flash ECU tuning from Eurocharged. Not every tuner is tuning the actual ECU as some are using piggyback modules at the moment so this goes to show Eurocharged's ECU tuning resources. The baseline you see is a 100% F10 M5 on a Dynojet and this is a very healthy car. 534 peak horsepower to the wheels is among the strongest graphs seen for the F10 M5.

93 octane fuel likely has something to do with it. After the install of the AMS downpipes and a Eurocharged custom dyno tune peak horsepower rises to 550 at the wheels. On the surface one might say 16 horsepower is not a large gain but one needs to look at the graph to see massive gains under the curve. With the new BMW turbo motors and how torque drops off toward redline as the turbos run out of steam major torque gains are going to come earlier in the powerband as boost is increased.

Once redline is approaching the gains level off but 48 peak pound-feet of torque gains are quite solid for a tune and downpipes on pump gas. This is something one will feel with the butt dyno the instant they put their foot down.

This graph is off as well. Look at the 5252 crossover. The stock dyno has been shortnend so I am curious as to exactly where the gains are. According to this, area under curve is more than 48 whp, but a more staggering 100+ rwhp at 5252 rpm.

Amigos even though there were ONLY 16 whp gain you forget to see that the torque numbers were a GAIN of 48 lbs of torque which is excellent, torque moves cars when needed!!

absolutely....I will take over 100whp in the midrange any day over x hp gain at the end of the run!

RPM as requested. Race gas would be great to play with, we should do that on the next one we do.

Downpipes make quite a bit of difference. Here is stock vs tuned. Quite interesting cars. I don't think we have seen another that is so picky about changes. We tuned 5 F10 M5's a few weeks back with the same software. One of them threw a CEL while the others were perfectly fine. Go figure...

Hmmm. Interesting. Nice torque gains. Area under the curve is definitely nice. Although there is a member on another board with catless DPs and RPi GTM (so, full straight pipes from the turbo back) and otherwise fully stock who made the same kind of gains in torque at the wheels but almost 3x that in horsepower...wonder how much of this car is due to the DPs and how much is due to the tune. Either way, great results.
